Work of the circuit The circuit consists of controlled pulse OSC circuit, trigger controlling circuit, differential circuit, light examining circuit, reshaping circuit and shining driving circuit (It is showed in picture 9-64.). When the interior light is strong enough the shining diode does not work. When the interior light is rather dim the controlled pulse amplifier starts to work and produces pulse signal. The signal drives shining diode to shine at a regular rate after being adjusted.
